The axle 1, of the improved machine'is' e uipped with transporting wheels 2,2. The s1 ls or frame bars 3, 3 which extend longitudinally beneath the axle a'ndw'hich are" suitably spaced and connected by means of arts in the several figures blocks 4 are supported adjustably by a compound lever including a member .5 which is fulcrumed on the axle with which it is connected by meansof a clip 6. A second 1cis suspended from the long arm of the layer 5. The short arms of the levers 5v and 7- are connected with the sills or frame bars by means of links 9, 10 which are located,

respectively, in fr ntand in rear of the axle. It will be seen th t by manipulating the long arm of the lever 7, the $1118 or frame bars may be lowered, as seen in Fig. 2, or

raised to the position indicated in Fig. 3. A plat-form 11 supported on the rear ends of the sills has an upright 12 with which the long arm of the lever 7 may be adjusta pin'or bolt 13jengaging one of a plurality of apertures 14 in the upright, thereby permitting the to be supported at variousmdjustments. It is also evident that by means of the compound lever arranged as described, the sills or frame bars even when of great weight will not require the services-0f more than one man for the purpose of raising or lowering the same. It may be here stated that the sills, as well as other parts of the machine, may be madeof timbers of Suitable dimensions to msure the requisite strength and weight for succonstructed mainly o meta ver 7 is fulcrumed on a link.8, whereby it P For the passage of the bolts 16, the spreaderbars are provided with bores 17 which may be made slightly flaring, as seen in Fig. 8, but which in any event are made sufficiently large to enable the sprea'der bars to be tilted or dipped with respect to the sills to a suitable position for crowning a road, as will be 20 clearly seen in Figs. 4 and? of the drawings,

it being understood that for grading or leveling the spreader bars may be adjusted to an approximately horizontal position. The spreader bars at each side of the machine are joined together by a longitudinal connecting bar 18, each of said connecting bars being connected with the Spreaders at one side ofthe machine by bolts or pivot members 19. A cross bar supported on the sills adjacent to the front ends thereof is connected with the bars 18 by means of links 21, said links bein adjustably connected with the bars 18 by bolts or fastening members'22: for. the reception of which each of the bars 18 is provided with a plurality of apertures 23, thereby enabling the angles of the spreaders with respect to the sills to be varied.

24 is a cross bar extending transversely across the sills and provided at the ends "thereof with knees 25 that are loosely supported on the connecting bars 18. The knees or knee blocks 25 may be slidably and adjustably connected with the crown bar 24 in order to adapt themselves to various adjustments of the bars 18 caused by adjustment of the spreaders to various-angles. The knee blocks are flexibly connected with the bars 18 by means of links 26. Fulcrumed on one of the sills 3 isa bell crank having a short arm 27 which is suitably connected with the crown bar 24. This connection, as seen in Fig. 6, may be brought about by mounting on the crown bar a recessed block or casting 28 having a pin 29 engaging a slot 30 in the lever arm 27. The bell crank also has an upwardly extending arm constituting a handle 31, whereby it may be manipulated, said handle being provided with a conventional stop member 32 engaging a rack segment 33, whereby the lever and related parts may be retained at various adjustments, It will be seen that by manipulating the bell crank the distance betweenthe crown bar 24 and the SlllS 3 may be varied. The crown bar is supported by the knees 25 which loosely engage the connecting bars 18 near the outer ends of the spreaders 15. By manipulating the bell crank to lift the sills, the inner ends of the spreaders which are connected with the sills by the bolts 16 will be lifted or tilted in an upward direction, as seen in Fig. 4, so that the road surface operated upon will be crowned to an extent regulated by the relative adjustment of the/ sills and the crown bar.

A tongue 34 which has been shown as being of the split or bifurcated type is con nected pivotally at its rear end with the sills 3 by means of a pin or bolt 35. The'forward end of the tongue may be supported on a tongue truck C, as indicated in Fig. 1 of the drawings, or it may be supported by means of an ordinary neck yoke from the necks of, the team; again, when a traction engine is employed, the front end of the tongue may be pivotally connected with the engine frame of truck and in this manner supported, and it may be stated that whenatraction engine is used, the length of the tongue may be considerably reduced. When the tongue truck G is employed, the draft animals may be attached to said truck by means of an evener D; when the tongue truck is not employed, the team may be hitched to an evener 5 36 suitably connected with the frame structure of the machine. The forward end of the frame structure is adjustably connected with the tongue by means of a bell crank fulcrumed at 37 on the sills, said bell crank having a short arm 38 whlch is connected by a link 39 with the rear end of the'tongue, and said bell crank havingalso an upwardly extending arm constituting a handle 40 which is equipped with the conventional stop member 41 engaging a rack segment 42, whereby the bell crank and associated parts may be retained at various adjustments.

A V-shaped scraper 43 is provided, said scraperbeing. connected by means of link bars 44 with the foremost spreaders 15, provision being made whereby the links 44 may be adjustably connected with the said spreaders. For the, purpose ofeffecting vertical adjustment of the scraper a lever 45 is provided, said lever being fulcrumed at 46 on the tongue 34, and said lever being connected with the scraper by means of a link 47. An upright 48 rising from the sill frame is provided with an adjustable pin or bolt 49, whereby the lever 45 may be retained at various adjustments. y

F rom. the foregoing description, taken in'; connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. When the machine is raised for transportation, as seen in Fig. 3 of the drawings, the frame structure will be bal- .anced on the axle, and will be also maintained by the bell crank whereby it is conany jerking and. oscillatory movement of the frame as the machine is carried along over the road. By manipulating the lever 77, the frame may be flowered-toward the ground, after which the lever arm 41 may be manipulated to effect a proper adjustment of the frame 'with respect .to the tongue, whereby the frame will again be maintained in an approximately horizontal position. By manipulating the lever arm 31, the Spreaders may be adjusted to crown the surface of the road to the desired pitch, and the scraper 43 may be adjusted in advance of the spreaders .by means of the lever 45. Thus, by proper adjustment of the parts. the center portion of the road may be scraped, and the material thus loosenedwill be deflected and spread in an -upward andinward direction by the spreader bars, thusleaving the road In good condition for subsequent travel and to shed water, 'Various other uses of the machine will readily suggest themselves, and the range of utility of the improved machine will be found to be very expensive. When the machine is made mainly'of 'wood, the various parts may be reinforced, and the scraper and spreaders may be .provided with steel blades as indicated in the drawings at 50. It is obvious that joints and connecting members of well known construction may .be employed in place of those herein shown and illustrated to enable the parts to be adjusted and manipulated in the manner herein set forth. The improved machine is simple'in construction, is capable of being produced at a moderatecost, and it has proven in actual practice to be thoroughly efficient for the purposes for which it is provided.
